Irwin 1837535 1/4" Magnetic Lobular Impact Nutsetters x 1-7/8" Length 

IRWIN Impact Performance Series lobular nutsetters are built for maximum durability, performance, and long lasting quality with impact tools. They are designed to drive the fastener from the side, rather than forcing the corners to turn, maintaining the true shape of the fastener and dramatically reducing breakage and damage from stripping. The lobular design also provides more clearance on the corners of the fastener where paint build-up often occurs. They are available with or without powerful rare earth magnets that hold fasteners securely in place. They have a black oxide finish that resists corrosion and increases the life of the nutsetter. Plus, with a 1/4" quick-change shank, they're designed to work with all types of impact and rotary drivers.
